Be i' known that I,.Jos1i MAsNADA a Spain, I and resident. of Humacao, county of Hum'acao, Porto Rico, West 'Indies,fhave invented a new and Improved Wall Construction, of which the tion. e This invention relates to improvements in concrete wall construction, an'obj ect of the invention vbeing tofprovide an improved re-inforced structure ofjithis kind which: will the cost of house building, A further objectisto provide a construction, either ofjthe solid wall or. hollow wall- 'i a f$ 1 nd exact deserip.

which will bestrong and durable in use, and which' willj'consist of a compara tively A further'objectisto a wall iconstruction which'maybe assembledcnot only cheaply, butrapidly so that the cost of materials and the ,cost of labor areFbothsub- A further o'bject' is to improved ing four grooved faces, so that'when a plurality Off these blocks are "assembled the grooves will form channels adapted to receive reinforcing rods.- I I With these and other objects in view,'the

- invention consistsin certain novel features ;of"constructi on, and combinations and arzz rangements of-partsas will be. more. fully hereinafter described and-pointed out in the claims. M

ploy a, plurality ofconcrete slabs orpanel square in shape, and relatively thin, their four meeting facesbeing provided"wit h a plurality'of grooves 2. v

The blocks are placed end to end, and one 'upon'V-the' other. Horizontal re inforcing rods '3' are? located in the'groove 2, between each tier offblocjksg. Vertical re -inforcing rods 41 are located in the groove-s 2 between the, columns of blocks, IWhenL'theblocks are assembledrthe grooves '2 will form" channels for'the reinforcing rods 3 and' 4:. j'

It will be'seenQtliat" at each corner of'each block the verticalreinforcing" rods 4 and blocks 1-. These {blocks are preferably 7 the horizontal reinforcing was 3 will cross.

After the rods are arranged. in pairs the 7 parallel pairs of rods are preferably connectedby tieqwires 15f f At each oint where the reinforcing. rods cro'ss, -that is at each" corner of each block, ce-

ment or mortar'6 is located in tlie groove 2 aroundthe reinforcing bars, and tie wires. The cement or mortar is of course applied as the wall is being constructed. After each appliedand the next tier laidon top.

The Wall's described" above' may upon any preferred kind of foundationfi'; This foundation may be of' brick-or conkinds of foundations" now commonly em: ployed.

The, verticalre-inforcingrods 4; are" an chored in the: foundation in any approved manner. I n I 1 -The'cornersofthe building are formed of "concrete columns 7 These columns. are

poured as the building is raised. Window andQdoorframesB are set in place as the air of blocks has been laid the mortar is be built 7 crete', oritheihous'esmay be builtiup'on :many

building progresses, and secured by concrete 1 or mortar tosthe panel blocks.

Referring particularly to the Figs. 1 and 2 of the drawings, I have illustrated four vertical reinforcing rods located in the corner columns. Upon each tier of panel blocks a tie wire 5 is located around all of the vertical re-inforcing rods inthe column. The corner columns maybe either flush with the W outer faces projecting slightly beyond the walls, as shown at 7.

The horizontal re-inforcing rods 3 have their hooked ends 10 anchored in the corner columns 10. Instead of employing only the usual form of horizontal re-inforcing rods,

as shown at 7 or may have their 3, horizontal re-inforcingtierods 3' are also used, the bend of these tie rods being located against one of the L vertical re-inforcing rods 4.

At the point where a partition 11 is joined to the wall, the panel blocks are spaced apart so that a. column of concrete .12 may be poured in the wall. The ends of the horizontal re-inforcing rods of the partition 11 areemhedded inthe column 12. Il1e. parti- 1 tions; are, constructed 5 in substantially the sameway' as'the w a-lls,.but,thinner blocks" are -us ed in the construction. WVhere two partitions meet at right.angles,"-the ends of the partition "blocks form a mold into which .is poured a concrete column, 1 3 1 having vertical 're inforcing rods; embedded therein and secured together by'tie, wires.
